+      <p>Since the last report &os; support for ThunderX has been
+	significantly improved and stabilized.  Semihalf contributions
+	include the following items:</p>
+
+      <ul>
+	<li>Support for the newest ThunderX chip revisions (Pass 2.0)
+	  and current Cavium firmware. Backward compatibility is
+	  maintained.</li>
+
+	<li>Moved to using pci_host_generic.c as a main driver for the
+	  internal PCIe bridge.  Significant rework of PCIe code to
+	  support both generic and ThunderX based platforms. </li>
+
+	<li> Serious networking performance boost and bug fixes: </li>
+	  <ul>
+	    <li>Fixed race condition on Rx path causing very rare
+	      ‘use after free’ issue</li>
+
+	    <li>Hardware L3 and L4 checksums support</li>
+
+	    <li>Hardware assisted TCP Segmentation Offloading
+	      (TSO)</li>
+
+	    <li>Support for software Large Receive Offload (LRO)</li>
+
+	    <li>Various improvements to Tx and Rx paths and
+	      configuration</li>
+	  </ul>
+      </ul>
+
+      <p>The driver supports all available Ethernet connections (1,
+	10, 30 Gbps) and system can can saturate 10 Gbps link (on Tx)
+	using 4 CPU cores.</p>
+
+      <ul>
+	<li>Significantly improved overall I/O performance:</li>
+	<ul>
+	  <li>Complete rework of copyin/copyout and bzero
+	    functionalities</li>
+	</ul>
+
+	<li>Other improvements:</li>
+	  <ul>
+	    <li>Support for interrupt to CPU binding (including
+	      GICv3/ITS backends)</li>
+	  </ul>
+      </ul>
+
+      <p>This work is integrated to the FreeBSD HEAD on on-going
+	basis.</p>
